Sale of 1.1MW Power-to-Gas Plant to EnergyStock

ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to announce that EnergyStock, a subsidiary of Gasunie, the Dutch gas transmission network operator, has purchased an ITM Power 1.1MW rapid-response PEM electrolyser. The sale was won in a competitive tender process and includes an after-sales support contract. The electrolyser will be located at EnergyStock's Zuidwending salt cavern storage facility in northern Netherlands, and the generated hydrogen will be either used on-site within EnergyStock's systems, or dispensed into tube trailers for supply to future hydrogen refuelling stations. Power will be delivered to the equipment via TenneT's high voltage electricity network.

ITM Power CEO, Dr. Graham Cooley, said: "We are delighted to be working with EnergyStock in the rapidly developing Power-to-Gas energy storage market. Power-to-Gas is the lowest cost long duration energy storage technique known. Power-to-Gas Energy Storage is joined up energy systems thinking - it exploits the virtues of an existing asset (the gas grid) to decarbonise both electricity and gas networks. Using excess renewable power to provide renewable heat combines two problems into one elegant solution."
